Aftermarket GRACO® 288817 Gun Repair Kit - SG2, SG3, SGPro (Non-OEM)

Manufacturer: Total Finishing Supplies

Part Number: 866451

Comparable OEM Part Number: 288817

Description: Total Finishing's part # 20-3448 is a direct-fit replacement for the GRACO® Gun Repair Kit designed for SG2, SG3, SG20, and SGPro spray guns. This comprehensive kit supports professional painting contractors and airless spray equipment specialists who maintain and rebuild these popular hand-held spray tools across jobsites, rental fleets, and service shops.

SG-series guns are workhorse applicators in commercial painting, industrial coating, and production spray environments. When internal components wear or fail, a complete repair kit streamlines the rebuild process by consolidating the packings, seals, springs, and other wear items needed to restore the gun to OEM performance specifications. Having this kit on hand minimizes downtime for contractors managing multiple guns or equipment technicians handling frequent service calls.

Common reasons for replacement:

• Fluid leakage around the gun handle or trigger area, indicating worn internal seals or packing degradation
• Inconsistent or weak spray pattern caused by damaged check valves or deteriorated elastomer components
• Trigger resistance or stiffness that prevents smooth actuation and control during spraying operations
• Loss of prime or failure to build pressure, pointing to compromised seals within the gun's fluid passage system

Manufactured to OEM-equivalent dimensions for proper fit and performance.
